PolySwitch Resettable evices Line-Voltage-Rated evices PolySwitch LVR devices help protect electric motors and transformers used in commercial and home appliances from damage caused by mechanical overloads, overheating, stall, lost neutral and other potentially harmful conditions. The LVR line-voltage product line of polymeric positive temperature coefficient (PPT) devices includes components that are rated for line voltages of 0V and 240V, for up to 2 of operating current at 20. They help protect against damage caused by both overcurrent surges and overtemperature faults, offer low resistance, and are compatibly sized with fuse solutions. Unlike traditional fuses, PolySwitch devices do not require replacement after a fault event. fter power has been removed and the overcurrent condition eliminated, the circuit is restored to normal operating condition. ompared to bimetal breakers, they offer greater flexibility, longer lifespan, and lower electromagnetic interference (MI). The PolySwitch LVR devices resettable functionality and latching attributes make them a reliable, cost-effective circuit protection solution for both intermittent- and continuous-operation motor applications. Their low resistance, fast time-to-trip, and low profile help circuit designers provide a safe and dependable product, comply with regulatory agency requirements, and reduce warranty repair costs. PolySwitch Resettable evices Line-Voltage-Rated evices series are suitable for line-voltage applications up to a continuous operating voltage of 240V /0V.

Warning : pplication Limitations for the LVR Product Line 1) Users should independently evaluate the suitability of and test each product selected for their own application. 2) This product should not be used in an application where the maximum interrupt voltage or maximum interrupt current can be exceeded in a fault condition. Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame. 3) PPT device is not a fuse - it is a nonlinear thermistor that limits current. Under a fault condition all PPT devices go into a high resistance state but do not open circuit, so hazardous voltage may be present at PPT locations. 4) The devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. 5) In most applications power must be removed and the fault condition cleared in order to reset a PPT device; however under certain unusual conditions, a PPT device may automatically reset. PPT devices should not be used in an application where an automatic reset could create a safety hazard, such as garbage disposals and blenders. ppropriate qualification testing should be performed. 6) It is the responsibility of the user to determine the need for back up or failsafe protection to prevent damage that may occur in the event of abnormal function or failure of the PPT device. 7) Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of a PPT device.this product should not be used in an application where the maximum interrupt voltage or maximum interrupt current can be exceeded by inductive spikes. 8) evices are not recommended for reflow soldering. 9) evice performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, or mechanical procedures for electronic components. 10) PPT devices are not recommended for installation in applications where the device is constrained such that its PT properties are inhibited, for example in rigid potting materials or in rigid housings, which lack adequate clearance to accommodate device expansion. 11) ontamination of the PPT material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices.
